There have been 12 possible reports of students contracting mumps at Fordham University's Rose Hill Campus in the Bronx.

Fordham University in the Bronx is working to contain a possible outbreak of mumps that has now spread to the school’s Lincoln Center Campus.

One case was reported Thursday at the school’s Midtown location, and four new cases at Rose Hill, for a total of 13 suspected cases of the viral disease, officials said.

“Fordham does not yet have laboratory confirmation that the illness is mumps, but that is the most likely diagnosis,” a University spokeswoman said in a statement.

All of the students with suspected infections have either returned home or have been isolated from other residents.

An employee at the school’s Bronx campus said all infected students were living in the University’s dormitories.

All Fordham students are required to have full vaccinations before attending the University, including the vaccination for mumps, measles, and rubella.

Symptoms of the highly contagious illness include fever, headache, muscle aches, tiredness and loss of appetite followed by swelling of salivary glands, according to the Centers for Disease Control and Prevention.

Typically mumps patients are contagious for two days prior to the outbreak of symptoms and five days after.

“Mumps in college-age men and women usually runs its course without any lasting effects,” the University’s statement continued. “Nonetheless, the University is trying to see what connection there might be among the affected students while stepping up the frequency and intensity of cleanings in communal bathrooms.”
